Tanzania Experiences Brief Internet Connectivity Degradation

Tanzania experienced a brief but significant internet connectivity degradation on Friday, June 27, 2026. The disruption began at 19:10 UTC and lasted for approximately 30 minutes, ending at 19:40 UTC. The primary impact was observed in active network reachability measurements across the country’s IPv4 address space.

Technical Details

The event registered a severity score of 627. The key affected metric was the ping-slash24 signal, which measures ICMP reachability across IPv4 /24 network prefixes. This signal showed a 24% drop from its peak value during the event window. Other network telemetry signals, including Border Gateway Protocol (BGP) control plane visibility, showed minimal deviation, indicating the disruption was primarily in the data forwarding plane. The cause has not been publicly attributed.

Network connectivity was reported restored by the end of the observation period.
